In diesen Bohrungen steckt ein Stift 16, der das Kupplungselement 8 dreh- und axialfest mit der Antriebswelle 7 verbindet.A coupling element 8 is placed on the end 7 "of the drive shaft 7 which is inserted in the central cavity 10. The end 7" has a transverse bore 19 which is aligned with transverse bores 18 of the coupling element 8. In these holes inserted a pin 16 which connects the coupling element 8 rotatably and axially fixed to the drive shaft 7.

Die beiden Kupplungselemente 8, 9 werden mittels einer Druckfeder 15 auf Distanz gehalten. Dabei ist die fordere Stirnseite des Halsabschnittes 36 nur geringfügig von der Stirnseite 1' des Gehäuses beabstandet oder berührt die Stirnseite 1' des Gehäuses. Das Kupplungselement 8 besitzt auf seiner zum Kupplungselement 9 hinweisenden Seite in Umfangsrichtung abwechselnd klauenartige Kupplungsvorsprünge 14 und dazwischen angeordnete Kupplungsaussparungen 11. Die Vorsprünge 14 und Aussparungen 11 wirken mit korrepondierend dazu gestalteten Kupplungsvorsprüngen 12 und Kupplungsaussparungen 13 des Kupplungselements 9 zusammen. Werden die Kupplungselemente 8, 9 aufeinander zu bewegt, so treten die Vorsprünge 12, 14 in die ihnen zugeordneten Aussparungen 11, 13 ein, so dass die beiden Kupplungselemente 8, 9 drehfest miteinander verbunden sind. Dies erfolgt durch einen axialen Zug auf den Knauf 2. Dabei gleitet das Kupplungselement 9 auf dem Abschnitt 7' der Antriebswelle 7 in Richtung des Endes 7" der Antriebswelle.The two coupling elements 8, 9 are held by means of a compression spring 15 at a distance. In this case, the demanding end face of the neck portion 36 is only slightly spaced from the end face 1 'of the housing or touches the end face 1' of the housing. The coupling element 8 has on its side facing the coupling element 9 in the circumferential direction alternately claw-like coupling projections 14 and interposed coupling recesses 11. The projections 14 and recesses 11 cooperate with properly designed to coupling projections 12 and coupling recesses 13 of the coupling element 9 together. If the coupling elements 8, 9 are moved toward one another, the projections 12, 14 enter the recesses 11, 13 assigned to them, so that the two coupling elements 8, 9 are connected to one another in a rotationally fixed manner. This is done by an axial pull on the knob 2. In this case, the coupling element 9 slides on the portion 7 'of the drive shaft 7 in the direction of the end 7 "of the drive shaft.

Wird der Knauf 2 losgelassen, so werden die Kupplungselemente 8, 9 von der sich entspannenden Kupplungsfeder 15 wieder getrennt.When the knob 2 is released, the coupling elements 8, 9 are separated again from the relaxing clutch spring 15.

Im entkuppelten Zustand lässt sich der Knauf 2 frei gegenüber der Antriebswelle 7 drehen. Im gekuppelten Zustand wird bei einer Drehung des Knaufs 2 das Schließglied 3 mitgeschleppt.In the uncoupled state, the knob 2 can rotate freely relative to the drive shaft 7. In the coupled state, the closing member 3 is entrained with a rotation of the knob 2.
